ESTE PROCESO DE CONTROL DE MOTORES ASINCRONOS EN PARALELO PARA LA REALIZACION POR EL CONJUNTO DE ESTOS MOTORES, DE UNA CONSIGNA DE PAR LLAMADA CONSIGNA DE PAR GLOBAL, COMPRENDE UN MANDO DE AQUEL DE ESTOS MOTORES QUE ES EL MAS CARGADO (M+), POR CONTROL DEL PAR PROPORCIONADO POR ESTE MOTOR (C+MES) TIENE UN VALOR DE REFERENCIA (C+CONS) DEFINIDO POR ADICION A LA CONSIGNA DE PAR MEDIO (CM, CCONS), OBTENIDA POR DIVISION DE DICHA CONSIGNA DE PAR TOTAL POR EL NUMERO (N) DE MOTORES, DE UN TERMINO CORRECTIVO QUE CORRESPONDE A LA SUMA ALGEBRAICA DE LOS DESVIOS DE PAR (DELTA C; +) DE CADA UNO DE ESTOS MOTORES (M1..MN), RESPECTO DEL MOTOR MAS CARGADO (MR), DIVIDIDO POR EL NUMERO DE MOTORES (N). This method for controlling asynchronous motors in parallel with a view to making, with all these motors, a set-point torque called the overall set-point torque, comprises a control for the one of these motors which is most loaded (m+), by automatic control of the torque provided by this motor (c+mes) to a set-point value (c+cons) defined by the addition to the mean set-point torque (cm,ccons), obtained by dividing the said total set-point torque by the number (n) of motors, of a corrective term corresponding to the algebraic sum of the torque deviations (Wc;+) of each of these motor (m1 ... mn), with respect to the most loaded motor (mr), divided by the number of motors (n).
